Mallory pivots from this family to the IOCs, detections, and named campaigns that touch your stack, and pages you when something new lands.
1 CVE Mallory has correlated with this family across public research and vendor advisories. Each row links to the full Mallory page for that vulnerability.
A Chinese advanced persistent threat tracked as Deep Panda has been observed exploiting the Log4Shell vulnerability in VMware Horizon servers to deploy a backdoor and a novel rootkit on infected machines with the goal of stealing sensitive data. The latest set of attacks documented by Fortinet shows that the infection procedure involved the exploitation of the Log4j remote code execution flaw (aka Log4Shell) in vulnerable VMware Horizon servers. | The latest set of attacks documented by Fortinet shows that the infection procedure involved the exploitation of the Log4j remote code execution flaw (aka Log4Shell) in vulnerable VMware Horizon servers to spawn a chain of intermediate stages, ultimately leading to the deployment of a backdoor dubbed Milestone ("1.dll").

The 1.dll module is the final payload, a backdoor that we have dubbed Milestone. Its code is based on the leaked source code of Gh0st RAT/Netbot Attacker and is packed with Themida.
4 distinct techniques documented for this family, organized by ATT&CK tactic.
Based on the leaked source code of the infamous Gh0st RAT but with notable differences in the command-and-control (C2) communication mechanism employed, Milestone is also designed to send information about the current sessions on the system to the remote server.
35 indicators attributed across vendor reports, sandbox runs, and researcher write-ups. Full values are available in Mallory.

2 sources tracked across advisories, community write-ups, and news. New activity surfaces here as Mallory finds it.
A backdoor deployed after Log4Shell exploitation of VMware Horizon servers. It is based on leaked Gh0st RAT source code with differences in C2 communications and is designed to send information about current system sessions to a remote server.
Windows backdoor/RAT derived from leaked Gh0st RAT/Netbot code. Delivered via Log4Shell exploitation of VMware Horizon followed by PowerShell and a loader chain. Establishes persistence as a Windows service (e.g., msupdate2) and supports typical RAT functions plus notable additions (e.g., session enumeration; some variants copy cmd.exe to dllhost.exe to evade monitoring). 2016 variants use XOR-encrypted comms and can create a temporary admin user (ANONYMOUS) to execute as admin; 2017 variants commonly Themida-packed and have forged/identical timestamps.
